Dark, USE THE EDIT BUTTON. You do not need to triple post then bump it an hour and a half later. People are not on 24/7.
Now first, figure in the nanobots of your battleship and you'll have much more than the fighter does.
Also factor in the SHIELD of the fighter, and the SHIELD batteries. That grants alot of extra defense. Also the fact that most of the time you hit the fighter, that not ALL the guns hit when it looked like they did, due to distance differences in the guns. So whats 90% inaccuracy with 1 gun, is more like 95% if your talking about all the guns. Cut your estimate in half right there. Then the shield (which automatically recharges every once in awhile) and the shield batts which recharge it quite a few times. That will drastically change your "equations." There are so many variables you did not even factor in. You can't possibly have an accurate description of the fight and how many time you hit him or his shields.
